IDK if worried would be correct, more like curious as to whats up. Why is the price at Cryptsy ~1XPM, and at Bter its at ~24ltc. I think it might be that they have a bunch of coins- and the reason for my post earlier.
From BTER Trade History

So during 2+1/4 hours with not one trade, the sell orders jumped from 14 to 22 and someone decided to buy it still?
(or the sell order jumped immediately after the buy at 14)
I wish you could see more trade history than 10 or so trades, who knows what's going on over at BTER.
